I'm very curious about this as well. I held waves previously and sold during the last rally but only recently started accumulating again. I never looked into this option and since I'm prepared to hold for long period of time, I've only recently started looking into leasing. There are many services, as you've pointed out, so would love to hear peoples experience with leasing.
I am surprised to have received no answer yet. When I google, I find many Waves lease services but I do not know which one is the best. I would therefore like to hear your opinion to separate the wheat from the chaff. I think there are certainly some who are already lease their waves and can give some tips. Would be very grateful. Thanks!
My favorite service is WavesGo because I'm using and their block explorer.
I'm using it for leasing from few months and until now I didn't have any problems with them. I can't tell you how fast is the support as I never needed to contact them.
